ANvIn BLOCK.

Application filed November 3, 1920. Serial No. 421,478.

To all whom t may concer/n: s

'Bel itknown that I, IRA A.,WEAvER, a citizen of the United States,:residing at Springfield, in the county of Sangamon and State ofIllinois, have invented certain new and useful Improvements in AnvilBlocks, of which the following is a specification.

Automobile wheel rims are of various forms andstyles, clincher, straightside, etc., and in service andvr during the changing of tires and rims`they are subject to numerous types of injuries and deformationsrequiring correction. All parts of such several shapes of rims arelikely to be damaged,-

and. adapted for use in the truing, shaping,

and repair of such injured vehicle wheel rims, whether they arelpermanently aliixed to their wheels or whether they are of thewell-known de'mountablel type.

One of the .objects'of the'invention is,

therefore, the provision of a block or anvil intended to be attached toand to overhang from a bench or other suitablesupport, such projectingpart, as well as that above'the bench or table, being employed in thevstraightening or truing operation and otherwise working on theseveralformsof rims.,

In Acase the damaged rim, such as onev which Yhas been injured or bentby a hammer blow, is not demountable from its wheelthe latter with therim `may, be brought tothe while therim is being straightened, withoutvremovingthe wheel from the vehicle. f f

"structural characteristics of an anvil blockv embodying thisinventionha preferred and VVV desirable embodiment of same has ybeenV'flange of `a ,two members.

lform block is desirablyr provided with a illustrated in theaccompanying drawings forming a part of this specification to whichreference should be had in connection with the following detaileddescription and throughout ythe several views of which drawings likereference characters 4refer tothe same parts. j

In these drawings:

Figure l shows such an anvil block in plan view applied to a benchforother appropriate support;l j V Figure 2 is .a central, longitudinal,vertical section through the appliance shown in Figure l; j

Figure 3 is an end view of thevblock applied to a bench and viewed fromthe overhanging end y Figures 4 and 5 illustrate in perspective types oftools adapted for advantageous employment in connection with such anvilblocks; 'A

Figure 6 shows the'use of the block or anvil for theV straighteningor'truing of the rim forming a permanent part of a wheel; Y

Figure 7 illustrates the overhanging part of the anvil block used inconnection Vwith the repairing of a demountablerim of the quickdetachabletype;

VFigure 8 depicts the employment of the block in connection with aclincher rim;

Figure 9 shows the improved form block used for straightening a flangeof a straight `side rim; and

Figure 10 portrays the employment of the block with a vvclincher rimforminga permanent part ofl its wheel. v

By referenceto these drawings, it will be seen that the improved anvilor block, formingthe Vsubject matter of thisinvention, has a flat bottomsurface 20 adapted to rest on a bench or other appropriate support 21to.v which; it may be conveniently yfastened by one or more screws orbolts 22,`

23 extended through registering holes in the The bottom of the anvilorcross rib orv projection 24 adapted to bear against the-edge of thebench to position the block thereon with the proper portion of VV,thelater overhangingthe edge of the bench To enable the publicjtounderstand the jutting or projecting part of the anvil or block istransversely curved or upwardly bowed to practically conform t-o theinner surface of a wheel rim of average diameter, such for example, asone of the quick detachable type permanently'aiiixed to its wheel as,for instance, one of the well-known wire wheels. The inner end of thiscurved surface, which may have a slightdepression 26 at this point ifdesired to more readily accommodate the grooved part of the rim,terminates in a vertical shoulder or wall 2T against. which the edge ofthe rim may bear while being operated upon. Such an employment of theanvil is illustrated in Figure 6, it being observed that the relativelynarrow surface permits the block to be used with such a rim withoutinterference with the wheel of which the rim forms a part. Ylrregularities or indentations in the shape of the rim may be` thusremoved by the employment of oneor more suitable tools, the block itselfconstituting an anvil or form member assisting in such truing operation.

It will be understood, of course, that if preferred the anvil or blockmay be detached from lthe bench and applied to the rim in the mannershown, beingheld in place by hand during its use. Such employment of thee block does not require the wheel being removed from the vehicle whilethe rim is being straightened.

Where the block and Wheel are associated together as illustrated inFigure 6, it may or may not be necessary or desirable to supplement thesupporting capacity of the block itself by other means for holding thewheel in position during the work done thereon.

The projecting part of the anvil is also supplied with a similarlycurved but more elevated surface 28 wider or broader than the face 25and having a similar shallow depression 29 adjacent to the uprightshoulder or wall 30 against which the edge of the rim may bear. Suchportion of the block, as

is illustrated in Figure 7, is especially designed or adapted for usewith rims of the quick detachable form which are demountable from theirwheels, and owing to the absence .of spokes and fellies such rims mayrest ,On this surface in a better manner and be more completelysupported by the block than could be experienced in attempting to usethe narrower section 25 which would perhaps necessitate .supplementalmeans to assist in holding the rim in place. It is, of course, thedemountability of such rim from its wheel that permits it to be morereadily Worked on on this particular part of the 2 block, all as isclearly depicted in Figure 7 The upwardly projecting section 3l ofthe Yblock, the outer face of which forms the surfaceBO referred toabove,'has a top flatI horizontal -face 32 designedto be used as astraightening block and this, as will be observed, is directly above thebench since the in Figure 8. The shape of this groove and f thecorresponding surface of the part 3l enables the operator by theemployment of proper tools to rid such a rim of any irregularities inits proper shape or form.

To the rear of such groove the block has i" a more elevated transverserib 35 with a downwardly curved top surface'SG shaped to conformsubstantially `to theouter face of a straight side rim of'averagediameter, the

front and rear faces 37 and 38 of such up- *if standing part flaring ordiverging somewhat to conform practically or in part to the innersurfaces of the flanges of such a straight side rim. The manner oftruingthe bent flanges of such a rim of this kind is illustrated inFigure 9 and any riveting or repairing required to be done on the lockor catch element of such a transversely-split rim can be performed onthe top or curved face 36 all as will be readily understood, theoperator working from the inner side of such rim. The vertical rim maybe shifted forwardly lor rearwardly to bring the one or the other flangeagainst its corresponding lface of the block or anvil as will be readilyappreciated. Lastly, to the rear of the part 35 the lblock is suppliedwith a. groove 39V substantially like the groove 34 and intended toreceive the edge portion of a clincher rim perinanently fixed to itsrwheeland which is disposed in a horizontal plane as illustrated inFigure l0 when this groovel is employed.`

No further explanationofthe construction Vand manner of usingtheanvilfis required, it

being apparent from the several illustrations and the abovedescriptionthat a block of'this kind may be advantageously used inrepairing all of the several styles of rims now on the market.

Those skilled in Vthis art will understand that the invention is notlimited and restricted to the precise and exact details of structureshown and described but that these may be modified within comparativelywide limits without departure from the substance and essence of theinvention and without the sacrifice of any of itsV substantial benefitsand advantages.
